The Schedule referred toin these Lettere Patent and matting part ofthe same# ",iujtlle e'ounty of Pasquotank andSt-ate of North Garolina, have invented a new l.anduseful Improvement in Gates; and I dolhereby declare the following to be a clear and exact description thereof, sufficient to enableothers skilled in thc art to which' my invention appertams to make and use the same,.reference being:-

'My invention is an improvement inthe class of an- `tfuatic opening and closing; gates, and consists in' hanging the gate' to a hinged beam, which is'to be proi jected in the direction opposite to that from which the horse or. vehicle is coming, by means of hinged platform and intermediate levers, so that,`when the horse or vehiclepasses overlone platform, and the rider or driver reaches the gate, he merely lifts theV latch, whereby thegate is released and immediately flies -open to its full extent.' A weighted swinging catch is'so located that the gate iscaught and heldopen until the horse or vehicle arrives on the other platform, when the gate will be lifted clear of the catch and The invention also consists in the peculiar construction of the latch and its connecting-parts, so that it l can he operated by 'tbe'action of the whee'lslof the l vehicle, or by persons, whether mounted or afoot.

A represents a gate, which may be of usual form,

gut, the present case, I construct it` as follows, (see a a' represent horizontal bars;

b l, vertical rods; and

c d, tbeverticaljbars to which the horizontal bars are attached.

t is a diagonal brace, extending from the top bar a l to near the upper end of tbe bar (l, and is formed with.

The gate A is hung, by suitable hinges, eyes, andv hookbolts,ror otherwise, to' a vertical beam, B,whose lower end is hinged at or near the bottom4 of lain up .right, O, which isfirmly' imbedded in or seeureltovthe: ground. l i

' I) representsaband, seeuredvtothe Iup'per end of the upright VGon the inner side thereof, and iuclosing the upper end ofthe hinged beam` B, whereb'ythe latteris allowed to swing on its axis, toa limited ex-` tent, ina longitudinal direction.

y To one `side of the hinged beam B Impivotabar or rod, E, which-extendsto .a lev'er, F, pivoted to post G, to which lever F is also .pivoted a bar or roth-H,

which is pivoted to a platform, J.- s

A s'imilar bar or rod, E, is pivoted to the other side -of the hinged beam B, and to it is connected a lever,`

F', pivoted to a post, AGr', and a bar or rod, H', is `pivoted tothe lever F'and to a platform,

The platforms .I are hinged to pieces"1isi11g from the ground, and are' pivoted to the levers .H H' by. frameworks K K'. l The horse or vehicle is to be driven over the .platfo'rms, and, in order to provide gradual-ascentto and, descent. from the said platforms, sills L L' are fixed to the front ends of theplatforms, and iifclines L" L'f, arrangedat the inside theref, said sills aud incliues .being so constructed as not to interfere with the .free motion of the platforms.

0n the posts G G 1 secure ears, whichsupport catches M, which are hung out of center and arranged in relation to the gate, whereby, when the lgate is open, the pin g on its frontend will strike the upper end of one of the, catches, ride-freely over it, andthen drop behind it, thegate thereby being firmly held open. l l

A latch, N, isarranged on ,an upright, P, opposite to the hinges` of the gate, which latch is s o constructed that it will allow the pin y' of the gate to automatically eng'age itself with said ,latch,'.and thus secure the gate, but be prevented from opening unless prop- .erly manipulated.

In the present case I construct thelatcb as follows: O O represent two blocks, which are arranged. to

slide vertically within an opening in the post P, and

to their lower ends are pivoted noses Q, which swing freely toward cach other, but are prevented from outward movement by confining plates or pieces on the post, said pieces or plates thus constituting stops, and serving to hold the gate when closed.-

The noses ot' the latch swing within a recess, R, but move vertically with vthe blocks O'O, when the latter are elevated or lowered,gthislieingaceomplisbed by means of a lever, S, as seeniu figs. Land 6.. l; This lever is hinged to theupright P, and projects on bothvsides through slots. formed in plates '.l, whih the nose on the other side, without disturbing the nose on its own side, and so with the operation ot the lever on the" opposite side.

A single lever thus operates the two noses of the latch without causing interference of each other, and

is designed to he manipulated by hand, whether the person is mounted or on foot.

An auxiliary means of operating the latch is by the wheels of vehicles. In this case, levers U are pivoted to the upright P, and are connected to the slotted plates '.l by pins, which pass through slots in the uppen end of said plates. i,

To the levers U are also pv'oted cross-bars V, to

whose lower end are pivoted levers W, wbich extend' ylongitudinally and have their free ends rest on transr verse levers .l

These levers are in position to be depressed by the weight of the vehicle which is de signed to enter the gate.

To prevent cattle, 85e., fiom operating said levers X, I provide guards Y, which. are'arranged to allow the free passage of the wheels, but prevent the feet of cattle, and animals generally, from interfering with the levers. For this pn are Baring, and the 1.

ground.

The operation is as follows:

se, the ends of the guard Ii' a. vehicle, or. horse, or other animal is coming in the direction ofthe arrow 1, fig. 2, its weight depresses the platform J'","and, through the4 intermediate bars and levers E'AF' H', throws the hinged beam in the' direction arrow 2. Tbeeenter of gravity of the gate is -thus changed, whereby, when the wheels of the vehicle ride over the lever 'X between lthe guards, as heretofore described, or when the rider or drirerof s are elevated above the` the horse or animal reaches the lever S N, and operates it, .the gate is free, and immediately flies open. It now catches on the-f latch of post G, and is thereby :firmly held.

The carriage or animal passes on, and, when it reaches the opposite platform, J, its weight depresses it, and, by means of the lovers E FH, the beam B is thrown in they dircctionof arrow, litting the gate clear of the latch which held it, and` changing its center of gravity. The gate .at once 'illes shut, and its 4pin engages with the latch N, as previously stated. l The operation of the gate in the direction opposite to arrow 1 is in reverse order to'that described.

In either ease, the mode of operation is the same.` The gate never swings open toward the party opening it, this being a serious objection to gates, the animals beiu'g frightened thereby.. I v l A In southern countries, where wood is vplentiful nnd finely nished gates are unnecessary, the gate may readily be made entirely of wood,a nd is thus in the reach of the humblest farmer.

Having thus described my invention,

What claim as new, and desire to secure by Let. ters Patent, is.

1. The hinged beam B, carryinglthe swinging gate, substantially as and for the purpose described.

2. The latch N, so constructed that it may be' operated by the hand-lever S, or the wheel-lever X, substantialiy as and for the purpose described.

3. The cross-bars V, levers U, levers W, and levers X, combined and operatingvwitb the latch.ll,substa'nl tially as andffor the purpose described. r I
